Hi Pete, would the small church yard at Thorne Coffin be a possible 'safe' site to run a moth trap (with permission!!). I have a portable actinic you could use if needed & I would be interested to see the results. I live in the next 1km square to the East and regularly follow this blog. Let me know if interested.

There was a notice board outside the church which may provide a clue as to where to ask for permission?I think your species total so far is very respectable in such an unpromising 1km square (I think I can call it that as a local resident!). I was planning on having a go in ST5317, so imagine my surprise when I saw you were doing it in the square immediately adjacent - quite a coincidence given there are over 240,000 1km squares in the UK!
